POSSIBILITIES OF USING 3D-PRINTING TECHNOLOGIES IN DESIGN AND PRODUCTION OF ENERGY RECOVERY MECHANISM WITH PNEUMATIC MOTOR

Abstract

Purpose. Investigate and propose new possibilities of using 3D-printing technologies in designing and manufacturing mechanism of energy recovery with pneumatic motor. Methodology. We have applied the experimental simulation of pneumatic motor, it’s construction and work. Energy recovery mechanism was simulated and it’s parts was created using 3d technology. Results. The existing technologies of 3D printing, types and structure of 3D printers for design and manufacture of special equipment for the energy recovery mechanism with a pneumatic motor are analyzed and considered in detail. The main materials for printing are considered, as well as carbon-containing materials for FDM printing, their properties and characteristics are considered in detail. The kinematic analysis of the printer mechanism for delta type 3D printing is carried out, the positioning errors for this mechanism type are determined. Measurement of the obtained part and processing of statistical data were carried out. The obtained holes of the part are compared with the given nominal values, and the absolute error for the outer and inner diameters is calculated. Originality. For the first time, the roughness of the delta robot rods was calculated, and the structure stress state under the applied forces action was calculated. Practical value. Having analyzed all the above information on the 3D printing using possibility in the special equipment manufacture and parts of the energy recovery mechanism with a pneumatic motor, it is possible to conclude that the special materials and the latest technologies use can reduce the recuperator weight with the required structural elements strength. The information and results obtained in this study actually correlate with similar researches. In addition, they also have a necessary and sufficient basis in order to conduct research on the use of 3D technology for the manufacture of parts and components. References 16, table 1, figures 14.
